The AR Battle Grip is a full sized rifle grip featuring a design that actually drives the user's hand up, and into the receiver/grip junction. Its texturing ensures a positive grip and the water resistant storage compartment is perfect for incidentals such as spare batteries, a full AR bolt, or even a few rounds of ammo. The ARBG fits all M4/M16/AR-15 series rifles and clones, Armalite AR-10 and Knights Armament Corp. SR-25/MK-11 Mod 0 or any rifle configured to take a Milspec M16/AR15 grip.
